Glowing praise for Joe Glassford’s books
I’m 68 years old and have been doing mechanical work for the last 50 years. I have done a lot of electrical work in those years and spent most of the time stumbling through it. I cannot thank you enough for putting this book out
Your book was such a great help to me. I am now not afraid to tackle diagnosing electrical problems. You’ve taught me more than my teachers at school.
Thank you for contacting us. We look forward to speaking with you.
